Swinging of the Botafumeiro

I have never seen a show like that.  But the first thing I thought was someone is going to get hurt. According to the free encyclopedia "There have been a number of accidents that occurred during the swinging of the Botafumeiro over the years. Apparently at one time, the Botafumeiro was attached to the rope with a hook which sometimes became disconnected.One of the most renowned accidents took place during a visit of Princess Catherine of Aragon. She was on a journey to marry the heir to the English throne in 1499 and stopped by the cathedral in Santiago de Compostela. While it was being swung, the Botafumeiro flew out of the cathedral through the Platerias high window. No one was reported to have been injured on this occasion.The ropes and other devices securing the Botafumeiro have also failed on May 23rd, 1622, and more recently in 1925 and July 1937. In 1622, the Botafumeiro fell at the feet of the tiraboleiros. In July 1937, the cords holding the Botafumeiro failed again, and hot coals were spilled on the ground.Current procedure is to attach the rope to the Botafumeiro with a set of "sailor's knots' ''.Monks ducking
